Tefilas Haderech Map

[ushdadude]

Does such a thing exist?

[AsherO]

wdym? Delineating when you have to say TH?

[ckmk47]

What would it have on it?
An alert when you've driven far enough to say tefilas haderech?

It is more complicated than that according to R Shlomo Miller and others. You need to know where the city ends to know where to start counting and you would measure that similar to tchumin.

A complicated algorithm to analyze structures in satellite images and their distance from eachother (and use?)

I guess something like this. I drove to the tip of Long Island today and was wondering if/when to say it.

That is the opposite of

מן המומחה

and most people would have difficulty at best in measuring tchumin themselves.

I meant based on already existing psakim, not based on their own measurements

There’s is a Sefer on the topic and he has maps in the back for many of the big cities.
But I imagine that the metzius can and does change.

A מומחה producing an algorithm is more reliable than a מומחה printing a book…

Years ago, my older aunt was ready to say tefilas haderech when we got on the Verrazano Bridge from Brooklyn. My father argued (as he always did when it came to this aunt) that the city continues in Staten Island. She insisted that 'was what we always did'. My father didn't buy it.

Your aunt was right. NYC is an עיר העשוי' כקשת in that area.

[gozalim]

What about some of the other nyc boundaries /bridges?

for things like techum that is unlikely

Yes, thank you for your service

I don't want to give a rule for all without a more thorough review, but if there is a specific one you are asking about I can review. The bridges between Brooklyn and Manhattan are all okay.

Rabbi Berkovits says Tefillas Haderech between Y-m and Bnei Brak/Bet Shemesh/Tel Aviv/North etc at the turn off to Bet Shemesh. He says it is the only area along the route you can say it at. If they take the 443, he says it in Shma Koleinu the Shemoneh Esrei before (assuming he knows in advance), otherwise without shem and malchus.

I'm assuming that can be employed for all safek situations
